High parasitic (no key) battery current drain. 240mA all the time.
The problem is battery dies when car isn’t used in more than a week. Not a problem if driven every day.
I measure battery current and found parasitic drain current to be 240mA or 0.24A of constant draw. The car spec on AlldataDIY is 50mA max.
I do have a remote start installed but I removed that and current only dropped about 10-15mA so not enough to matter.
I did leave the car for a couple hours thinking some of the logic circuit would drop in power over time as they fell into low power sleep modes. I didn’t happen. When you first connect battery current spike up to 1.5A and then drops to the 240mA about 30 seconds later (when radio display goes blank). It never goes low than this, even hours later.
I did find the current is on the two legs on the battery box served by fuse F19 and F21. If I pull both of these fuses the current falls to zero.
I am sure it isn’t leakage at the alternator as well. I disconnected the wire to the alternator thinking leaky diodes/rectifiers where the path of leaky current. It made no difference. There was no measureable leakage current through the alternator.
A few questions:
- Could AlldataDIY just have it wrong and the key off current really is 200-220mA for this car?
- The wiring diagrams are vague on AlldataDIY when it comes to the logic circuits. Its hard to say which lines should use how much current. Is there a way to get more detail and how my 200+ mA current should be broken down?
- The radio alone seems to be 70 mA by itself which is over the 50mA alone.
Any ideas or suggestions appreciated. Obviously this is a subtle problem because there isn’t an obvious or horrendous current drain. It’s still a problem though.
I have an ‘06 Escape that I recently bought from a relative that has 80,000 miles. It was bought from a dealer previous to the relative, so it’s history is not complete. It recently started lighting both the "ABS" and "4WD" trouble lights. This happened after a rain and both at the same time, and persists intermittently now. The "4WD" blinks then goes away for a few minutes, apparently meaning a temporary problem. The ABS stays lit, then both lights go away at shutdown for awhile it seems.
My thought, is that the sensors are the same that tell ABS and 4WD to engage when the sensors detect wheel slippage. They may be failing, or still wet somehow, and this is what is causing the trouble lights to appear. I’m wondering if I replace the sensors if that will make the problem go away. I have a Haynes manual for the Escape, which I like. However they recommend going to the dealer for these kinds of problems. I always try and avoid getting ABS for this very reason – the complexity factor. Any thoughts you might have would be greatly appreciated.
Sincerely,
Dave
Does anyone know
1) What would cause this?
2) What relay to check in the power distribution box?
Thank you,

After the first couple of weeks we are only achieving about 24.5 mpg in non-Interstate driving. We live in SC so itis rather warm and cold batteries are not a factor.
We have not checked with the dealer and I figured I solicit feedback from other owners first.
Is there anything that needs to be observed as far as driving style is concerned given that my wife had been driving a V8 SUV for the past few years?:driver:
I had seen that there was a issue with cloth seats on older models. Does anyone else have this problem? Or does anyone know if there is a solution to fix it?
Thanks
